## Early life

Benjamin Abraham Horowitz was born in London, England and raised in Berkeley, California, the son of Elissa Krauthamer and conservative writer and policy advocate David Horowitz. He is of Ashkenazi Jewish descent. Horowitz's great-grandparents were Jewish immigrants from the Russian Empire who arrived in the U.S. in the mid-19th and early 20th centuries.
Horowitz earned a BA from Columbia University in 1988 and an MS from UCLA in 1990, both in computer science.

## Career

Horowitz began his career as an engineer at Silicon Graphics in 1990. In 1995, he joined Marc Andreessen at Netscape as a product manager. From 1997 to 1998, Horowitz was vice president for the Directory and Security Product Line at Netscape. After Netscape was acquired by AOL in 1998, Horowitz served as Vice President of AOL's eCommerce Division.
In September 1999, Horowitz cofounded Loudcloud with Andreessen, Tim Howes, and In Sik Rhee. Loudcloud offered infrastructure and application hosting services to enterprise and Internet customers such as Ford Motor Company, Nike, Inc., Gannett Company, News Corporation, the United States Army and other large organizations. Horowitz took Loudcloud public on March 9, 2001.
In June 2002, Horowitz began a transformation of Loudcloud into Opsware, an enterprise software company. He took the first step by selling Loudcloud's core managed services business to Electronic Data Systems for $63.5 million in cash. This transaction transferred 100% of Loudcloud's revenue to EDS while the company was publicly traded on NASDAQ. Beginning with EDS as its first enterprise software customer, Horowitz grew Opsware to hundreds of enterprise customers, over $100 million in annual revenue, and 550 employees. In July 2007, Horowitz sold Opsware to Hewlett-Packard for $1.6 billion in cash.
Horowitz was Loudcloud's and Opsware's President and Chief Executive Officer for the entire history of the company. Along the way, shares of Opsware IPO'ed at $6, sank to $0.35 per share at its nadir and traded at $14.25 a share at the time of its sale to HP.
Following the sale of Opsware to Hewlett-Packard, Horowitz then spent one year at Hewlett-Packard as Vice President and General Manager in HP Software with responsibility for 3,000 employees and $2.8 billion in annual revenue.

### Andreessen Horowitz

On July 6, 2009, Horowitz and Andreessen launched Andreessen Horowitz, to invest in and advise both early-stage startups and more established growth companies in high technology. Andreessen Horowitz began with an initial capitalization of $300 million and within three years had $2.7 billion under management across three funds.

## Personal life

Horowitz lives in Las Vegas with his wife, Felicia Wiley Horowitz. They married in 1988 and have three children.
In July 2024, Horowitz announced he will donate to Super PACs that support Donald Trump's presidential campaign. In October, however, Horowitz announced that he and his wife will be making "significant" donations to groups that support Kamala Harris' campaign, citing their friendship dating back over 10 years.
